I could really use some help. I have a 98 olds delta 88 that wont start. It was running, but running poorly. It then died on the side of the road. I checked the fuel pressure regulator and found that there was fuel in the vacuum line so I replaced that.
When I went to try and start it, it wouldnt even crank over. I pulled the plugs and was able to turn it over, and it blew a bunch of liquid (gas?) out of one of the cylinders. I think it was hydraulic locked.
I cleaned the plugs and replaced them, and when it still wont fire. I know that I have spark coming off of all three coil packs, and as far as I can tell I have fuel. You can smell it and when I check the pressure relief valve on the regulator ther eis fule there.
I even tried giving it a shot of ether and it wont run on that either. Occasionally it will backfire, but it wont start.
Someone suggested that the Intake Manifold (plenum) might be bad so I replaced that and went thru the exercise of clearing the cylinders again but it still wont start.
I have started disassembly to check the timing belt to see if it broke, but have yet to get the harmonic balancer off, I guess I need a puller, I have the bolt out, but havent got the balancer off yet.
If the timing belt is broken, I will at least know what might have happened, and then I need to decide if it is worth repairing. If the timing belt is ok, (I will change it anyway), what else could it be ?
I have seen some mention of a CPS (crankshaft position sensor), if it goes out could it affect the timing enough so it wont run ?
Any help would be appreciated.
